To aZZ whom it may concern:

Be it known that we, LOUIS HENRY SoLoN and Jenn McMAnoN, of Mendota, inthe county of La Salle, and in the State of Illinois, haveinventedcertain new and useful Improvements in Devices for )Veighing orMeasuring Grain; and we do hereby declare that the following is a full,clear, and exact description thereof.

Our invention relates to the weighing or measuring of grain from athrashing-machine as it comes from the elevator and is conveyed to awagon or other suitable receptacle; and it consists in certainpeculiarities of construction, will be fully set forth hereinafter andpointed out in the claims.

In the drawings, Figure 1 is a side elevation of our said device, partlybroken away to bet: ter show the construction and with the bottom of themeasure closed; and Fig. 2 is a vertical central section of the samewith the bottom of the measure open.

A is the elevator, of ordinary construction, and B the head of the same.

0 is a scale beam or lever, which is balanced directly over the head ofthe elevator, with a movable weight, D, (held at any desired adjustmentby the set-screw D,) for the different kinds of grain, and saidscale-beam is pivoted between the arms of a lug, E, on the front end ofthe elevator-head, while from the short arm 0 of this scalebeam issuspended the bail F F l?" of the hinged bottom H of the measure G.Secured to the pintles a of the said bail-arms F on the said hingedbottom are the arms I of another bail, which arms are themselvesprovided with pintles b, by which they are pivoted to vertical straps J,depend ing from the elevator-head B, and the bail I ends in a loop oreye, 0, which receives the lower end of a rod, K, (said end beingpreferably screw breaded and fitted with a nut or with collar, (2,) theupper end of this rodK being hinged to a lug, c, on the under side ofthe hinged cut-01f L, which closes the bottom of the elevator-head, andwhich,when dropped, bears against a stop, f, in an arm or bracket, M,projecting from the elevator A.

The measure G is connected to the elevator A by means of links N, whilea cross-rod, 9, extending from one strap J to the other, prevents themeasure from droppingtoo far down by coming in contact with said linksN, as shown in Fig. 2. A set-screw, h, projecting from lug E preventsthe scale beam 0 from going beyond its center of gravity when raised,and when the said beam 0 falls in the opera tion of our device its freeend strikes the trans verse arm 2' of a register, 0, which latter may beof any approved pattern, so as to register the quantity of grainthrashed as fast as it is measured or weighed.

1? represents ordinary tightening devices secured to the journals A ofthe elevators in the usual manner.

The operation of our device will be apparent from the foregoingdescription of its construction. As the grain is elevated (which is doneon the side nearest the measure, as indicated by the arrow in Fig. 2) itfalls on the cut-off L, and as it accumulates the weight of it openssaid cut-off, which forms a spout leading to the measure G, and thisdownward movement of said cut-off depresses its hinged rod K and thefree end 0 of the bail 1, thereby raising the pivoted ends of the armsof said bail Land wit h them the bottom H of the measu're, the scalebeam0 falling at the same time and its free end striking the transverse armi of the register Oand registering one measure full ol'grain. The momentthe measure gets its proper weight it overcomes the weight D on thescale beam, and the latter begins to rise and the measure G to descenduntil its links N strike the cross-bar g, the downward movement of themeasure serving, by the described connection ofparts the moment itsbottom Hopens, to raise (through bail l c and rod K) and close thecut-oft L, the bottom opening when the erossrod g is reached, asdescribed, and the scale-beam O raised to about a vertical position,whenthe grain is dumped from the measure, sliding off the open inclinedbottom H into any suitable receptacle, and then the ac tion justdescribed is repeated.

The great advantage of our device is that its action is entirelyautomatic, and neither the cut-off nor grain-measure bottom has to beprovided with any hook, catch, latch, or trip; but one of these partsregulates the closing and opening of the other at the proper times inregular alternation, thus assuring accuracy of action, combined withgreat simplicity of construction.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. In a device for automatically weighing or measuring grain, thecombination of an elevator and measure with a cut-offand a rod directlypivoted thereto, and a bail pivoted on a fixed support and connectingsaid rod and the hinged bottom of the measure, whereby said cutoff isclosed by the downward weight of the measure and opened by the weight ofgrain accumulating thereon while the measure is dumping.

2. In a device for automatically weighing or measuring grain, thecombination of an elevator and a cut-off hinged to the head thereof, aweighted scale-beam pivoted to said head,'a

measure connected by links to the elevator and having a pivoted bottomattached by a bail to the said scale-beam and by another bail to strapsdepending from the elevatorhead, said straps being connected by a cross-
